INCORPORATION BY REFERENCE

Firearm buttstocks that are displaceable along a firearm between acollapsed position and an extended position are generally known, such asthose described in U.S. Pat. Nos. 6,925,744 and 7,363,740 issued to thepresent inventor, each of which is hereby incorporated herein byreference in its entirety.

BACKGROUND

The subject matter of the present disclosure broadly relates to the artof firearms and, more particularly, to a buttstock assembly for afirearm that provides increased strength and/or performance incomparison with known buttstock constructions. A firearm that includessuch a buttstock assembly and a method of assembling a firearm buttstockare also described.

It is generally believe to be desirable to reduce the weight of firearmsthat are hand carried as weapons, such as by military and/or lawenforcement personnel, for example. This is advantageous because suchweight reductions can permit additional equipment to be carried in placeof the weight that has been eliminated. For example, firearm buttstockshave been developed that include compartments for carrying additional,alternative and/or replacement components for the firearm, such asadditional batteries for an electronic instrument or laser sight, forexample. Alternately, any weight reductions that are achieved can simplyreduce the overall load that is being carried. This, of course, is alsoadvantageous.

Many known buttstocks for firearms are produced from polymericmaterials, rather than being constructed from metal. The use ofpolymeric materials can be beneficial for balancing factors such asweight of the buttstock assembly, manufacturing costs associated withthe production of the buttstock assembly and performance characteristicsof the buttstock assembly. As such, firearm buttstocks manufactured frompolymeric materials are well known and widely used. Notwithstanding thecommon usage and overall success of such known polymeric buttstocks,some issues remain that undesirably effect the durability and robustnessof firearm buttstocks formed from polymeric materials.

It is well known that firearm buttstocks are used as a bracing point tosteady and control a firearm during use. For example, the buttstock isoften used as a shoulder brace, such as when the weapon is being firedfrom a standing, sitting or kneeling position. For this reason, firearmbuttstocks commonly include a cushion or butt pad that is secured on adistal end wall of the buttstock.

As another example, the buttstock can rested on a supporting surface tosteady the firearm, such as when the firearm is being discharged from aprone position. It will be appreciated that any available supportingsurface may be used under such conditions and that the supportingsurface is often a hard, rough surface, such as dirt, rock or concrete,for example. Under these conditions, the bottom surface of the buttstockthat is resting on the supporting surface can become worn due toabrasion and actions engagement with the hard, rough surface.Accordingly, it is desirable to develop a firearm buttstock assemblythat is capable of providing improved wear performance and/orcharacteristics under such conditions of use. It is also believeddesirable to provide such improved wear performance and/orcharacteristics without substantially increasing the weight of thebuttstock assembly.

It is also well known that equipment carried by military and lawenforcement personnel can be employed for a wide variety of alternativeuses in addition to the primary purpose or use of the particular pieceof equipment. In the case of a firearm, it will be appreciated thatmilitary and/or law enforcement personnel will often use the buttstockof a rifle to deliver impact forces, in addition to using the weapon inthe normally intended manner (i.e., to fire projectiles). For example,military and/or law enforcement personnel may use the buttstock to forcean object into a desired position, to smash a window or door or tostrike an opponent in close quarters combat.

Known firearm buttstocks that are formed from polymeric materials arewell suited for balancing factors such as weight, cost and performanceassociated with normal use conditions of a firearm. Unfortunately, knownfirearm buttstocks are less well suited for the various alternativeconditions of use to which the buttstocks are often put, such asdelivering impact forces, for example. As such, it is believe desirableto develop a firearm buttstock construction that improves the strengthand robustness of firearm buttstocks, such as those formed frompolymeric materials, for example. It is also believed desirable toprovide this increased strength and/or robustness without substantiallyincreasing the weight of the buttstock assembly.

DETAILED DESCRIPTION

Turning now to the drawings, wherein the showings are for the purpose ofillustrating exemplary embodiments of the subject matter of the presentdisclosure only and not for the purposes of limiting the same, FIGS. 1-7illustrate a firearm 100 that includes a receiver extension 102 and abuttstock assembly 104 supported on the receiver extension. It will berecognized that the subject matter of the present disclosure is capableof broad use on or otherwise in connection with a wide variety offirearms of different types, kinds, configurations, constructions and/orarrangements, such as, for example, may be produced by differentmanufacturers and/or as different models from any particularmanufacturer. As such, it is to be understood that the particularembodiment shown and described herein is merely one example of asuitable firearm and buttstock assembly, and that a firearm and/orbuttstock assembly of any other type, kind, configuration, constructionand/or arrangement in accordance with the subject matter of the presentdisclosure could alternately be used.

As shown herein, receiver extension 102 extends longitudinally betweenopposing first and second ends 106 and 108. First end 106 is adapted toconnect to a receiver (not shown) of firearm 100 in a conventionalmanner, such as by using a plurality of interengaging threads 110 and analignment feature (e.g., a keyway or slot) 112, for example. Receiverextension 102 also includes a first wall 114 that extends longitudinallybetween first end 106 and second end 108. The exemplary embodimentshown, first wall 114 has an outer surface 116 that defines anapproximately cylindrical cross-sectional outer shape of at least aportion of the receiver extension and an inner surface 118 that at leastpartially defines a passage 120 extending lengthwise through at least aportion of the receiver extension. It will be appreciated that receiverextensions, such as receiver extension 102, for example, are generallyknown and that the same often take the form of hollow tubes, such as isshown in the present exemplary embodiment. It will be appreciated,however, that alternate constructions can optionally be used.

Receiver extension 102 is also shown as including an alignment rail 122that extends longitudinally along the first wall 114. Alignment rail 122projects radially outwardly from outer surface 116 and has a somewhatrectangular-shaped cross section. An elongated slot 124 is formed intothe alignment rail and a plurality of retaining features is providedwithin slot 124. The plurality of retaining features is shown asincluding openings or cavities 126 that extend inwardly into alignmentrail 122 and are disposed in longitudinally-spaced relation to oneanother along the length of slot 124 formed in the alignment rail.

Buttstock assembly 104 is shown as including a buttstock body or frame128 that extends longitudinally between a first frame end 130 and anopposing second frame end 132 such that a nominal overall length of thebuttstock frame is generally defined therebetween, as is indicated byreference dimension LGT in FIG. 4. Buttstock frame 128 also includesopposing first and second sides, which are generally identified by itemnumbers 134 and 136 in FIG. 4 and at least partially define a nominaloverall width of the buttstock frame, as is indicated by referencedimension WTH in FIG. 4. Furthermore, buttstock frame 128 extends in agenerally heightwise direction between a top portion and a bottomportion, which are generally identified in FIG. 3 by item numbers 138and 140 and at least partially define a nominal overall height of thebuttstock frame, as is indicated by reference dimension HGT in FIG. 3.

Buttstock body 128 includes body wall 142 that at least partiallydefines a first passage 144 extending lengthwise between first andsecond ends 130 and 132 of the buttstock body. First passage 144 has alongitudinally-extending axis AX1 and is adapted to cooperativelyreceive receiver extension 102. As shown herein, first passage 144 has across-sectional shape that is at least partially defined by a first wallportion 146 and a second wall portion 148. In a preferred arrangement,first wall portion 146 at least partially defines an approximatelycylindrically-shaped portion of passage 144 that is complimentary toouter surface 116 of first wall 114 of the receiver extension.Additionally, second wall portion 148 at least partially defines anapproximately rectangularly-shaped portion of passage 144 that iscomplimentary to alignment rail 122 of the receiver extension.Furthermore, other wall portions can also, optionally, be included. Forexample, first passage 144 can also be at least partially defined bythird wall portions 150 that are disposed on opposing sides of thebuttstock body and at least partially define longitudinally-extendinggrooves 152.

Buttstock body 128 is also shown as including an end wall 154 that isdisposed in approximately transverse relation (e.g., perpendicular) toaxis AX1 and a bottom wall 156 that extends along bottom portion 140 ofthe buttstock body. A connecting wall or web 158 acts to generallyinterconnect body wall 142, end wall 154 and bottom wall 156. Buttstockbody 128 can also optionally include one or more additional featuresand/or components. For example, buttstock body 128 is shown as includingan elongated slot 160 disposed along top portion 138, such as may beused to receive a strap or harness (not shown), for example. As anotherexample, an opening 162 can extend through or otherwise be provided onconnecting web 158, such as could be used to receive a swivel fittingconnector (not shown) for a strap or harness, for example. As a furtherexample, a compartment 164 could be formed into connecting web 158adjacent end wall 154 and/or bottom wall 156. Buttstock body 128 couldalso include a cover 166 for the compartment and any one or moreadditional features for securing the cover on or along the connectingweb, bottom wall and/or end wall, such as a hinge pin 168, for example.As still another example, buttstock body 128 could include a series oflongitudinally spaced openings 170 formed through body wall 142 incommunication with grooves 152. A corresponding plurality oflongitudinally spaced holes 172 could be formed through connecting web158. Openings 170 and holes 172 can be used to selectively mount andsecure one or more accessories on either or both sides of buttstockbody, such as has been described in detail in U.S. Pat. Nos. 6,925,744and 7,363,740, for example, which are issued to the subject inventor andhave been incorporated herein by reference, each in its entirety.

Buttstock body 128 also includes a second passage 174 that extends in anapproximately transverse orientation (e.g., perpendicular) to firstpassage 144. Second passage 174 has a second axis AX2 and is shownextending in a generally widthwise direction through buttstock body 128between first and second sides 134 and 136 such that an open end (notnumbered) of second passage 174 is formed along each of first and secondsides 134 and 136. In an alternate arrangement, the second passage couldextend into the buttstock body from only one of the first and secondsides, such that the second passage would only include one open end.Second passage 174 can be of any suitable size, shape, arrangementand/or configuration. For example, in the exemplary arrangements shown,second passage 174 is defined within buttstock body 128 by a first orupper surface 176 disposed toward top portion 138 of the buttstock bodyand a second or lower surface 178 disposed in spaced relation to thefirst surface in a heightwise direction toward bottom portion 140 of thebuttstock body. In one preferred embodiment, the first and secondsurfaces of second passage 174 extend approximately lengthwise along thebuttstock body and approximately widthwise between the first and secondsides of the buttstock body. Additionally, second passage 174 can beformed or otherwise at least partially defined by a first or forwardside wall 180 disposed toward first end 130 and a second or rearwardside wall 182 disposed in spaced relation to the first side wall in alengthwise direction toward second end 132. In one preferred embodiment,the first and second side walls extend widthwise between the first andsecond sides of the buttstock body and in a heightwise direction towardthe top and bottom portions of the buttstock body.

Buttstock body 128 further includes a third passage 184 that extends inan approximately transverse orientation (e.g., perpendicular) to firstpassage 144 and second passage 174. Third passage 184 has a third axisAX3 and is shown extending in a generally heightwise direction throughbuttstock body 128. In a preferred arrangement, third passage 184 willextend between a first open end (not numbered) in communication withfirst passage 144 and a second open end (not numbered) formed alongbottom wall 156. Third passage 184 also extends through second passage174 such that the first and second passages can be in communication withone another through the third passage. In one exemplary arrangement,third passage 184 is approximately cylindrical. It will be appreciated,however, that any other shape and/or configuration could alternately beused. Buttstock body 128 can optionally include a fourth passage 186that extends through first wall portion 146 of body wall 142 inapproximate alignment with third passage 184.

Buttstock assembly 104 also includes a transfer member 188 and aretaining member 190 that is adapted to abuttingly engage transfermember 188, such as, for example, to transmit forces acting on theretaining member to buttstock body 128 through transfer member 188.Transfer member 188 can be of any suitable size, shape, form and/orconfiguration and is preferably cooperative with second passage 174 suchthat the transfer member can be at least partially received therein. Inthe exemplary arrangement shown and described herein, transfer member188 includes an inner side wall 192 that at least partially defines anopening 194 extending through the transfer member. Transfer member 188also includes at least one outer side wall that at least partiallydefines an outer peripheral shape of the transfer member. As shownherein, transfer member 188 has a plurality of outer side walls 196defining a generally rectangular (e.g., square) shape. In a preferredarrangement, at least one outer side wall of the transfer member willabuttingly engage a side wall of the second passage such thatlongitudinally-acting forces can be transferred between buttstock body128 and retaining member 190 through abutting engagement with transfermember 188.

Buttstock assembly 104 can also, optionally, include a biasing memberoperatively connected between buttstock body 128 and transfer member188. It will be appreciated that a biasing member of any suitable type,kind, configuration and/or construction could be used. For example, inthe embodiment shown herein, the biasing member includes a springelement 198 that includes a spring wall 200 having an opening 202 formedtherethrough. Spring element 198 is also shown as including a pair ofopposing retaining walls 204 that are adapted to abuttingly engagetransfer member 188. The biasing member can be operatively connectedbetween the buttstock body and the transfer member in any desiredmanner, such as by inserting spring element 198 into second passage 174between transfer member 188 and one of upper and lower surfaces 176 and178, for example. In a preferred arrangement, opening 202 is positionedin approximate alignment with third passage 184 such that retainingmember 190 can extend through spring element 198 together with transfermember 188.

Retaining member 190 can be of any suitable size, shape, configurationand/or arrangement for retractably engaging receiver extension 102. Inthe exemplary arrangement shown herein, retaining member 190 extendslongitudinally between opposing first and second ends 206 and 208.Retaining member 190 is at least partially received in third passage 184and is oriented therein such that first end 206 is in communication withfirst passage 144 and second end 208 projects outwardly from buttstockbody 128 along bottom portion 140 thereof. As such, it will berecognized that retaining member 190 extends through opening 194 intransfer member 188 and opening 202 of spring element 198, if provided.

Retaining member 190 is shown as including a first outer surface 210disposed toward first end 206 and a second outer surface 212 disposedtoward second end 208. First outer surface 210 is preferably of a sizeand shape that is complimentary to cavities 126 formed in receiverextension 102 and opening 194 formed in transfer member 188. As shown,first outer surface 210 at least partially defines a first portion (notnumbered) of the retaining member that has an approximately cylindricalshape. Second outer surface 212 is preferably of a size and shape thatis complimentary to third passage 184 such that the retaining member canbe displaced in a heightwise direction therealong. In the exemplaryarrangement shown, second outer surface 212 at least partially defines asecond portion (not numbered) of the retaining member that has anapproximately cylindrical shape but has a cross-sectional dimension thatis less than the cross-sectional dimension of the portion formed byfirst outer surface 210. As such, a shoulder wall 214 can be providedthat extends radially between first and second outer surfaces 210 and212. It will be appreciated, however, that any other shape,configuration and/or arrangement of outer surfaces could alternately beused.

Buttstock assembly 104 can also optionally include a biasing member thatis operatively connected between buttstock frame 128 and retainingmember 190 to bias or otherwise urge first end 206 of the retainingmember toward first passage 144 of the buttstock frame. It will beappreciated that a biasing member of any suitable type, kind,configuration and/or construction could be used. For example, in theembodiment shown herein, the biasing member includes a spring element216 (FIG. 7) that is compressively positioned between buttstock frame128 and shoulder wall 214 of retaining member 190. In a preferredarrangement, third passage 184 will include a first portion 218 that hasa cross-sectional dimension complimentary with first outer surface 210of the retaining member and a second portion 220 that has across-sectional dimension complimentary with second outer surface 212 ofthe retaining member such that a shoulder wall 222 extends radiallytherebetween. In such case, spring element 216 can be a compression-typecoil spring dispose between shoulder wall 214 of the retaining memberand shoulder wall 222 of the buttstock body. It will be appreciated,however, that any other arrangement and/or configuration couldalternately be used.

As described above, retaining member 190 is retractably disposed withinthird passage 184 such that first end 206 is biased or otherwise urgedtoward first passage 144 to abuttingly engage slot 124 and cavities 126.This permits buttstock assembly 104 to be longitudinally disposed in anyone of two or more different positions along receiver extension 102 offirearm 100. To permit the buttstock assembly to be displaced from afirst position to a second position, retaining member 190 is retractedin a heightwise direction a sufficient distance to permit the second endof the retaining member to disengage the cavities of the receiverextension. It will be appreciated that the retaining member can beretracted in any suitable manner, such as by applying a force to theretaining member in a heightwise direction, as is indicated by arrow FORin FIG. 7. It will be appreciated that such a force can be applied inany suitable manner. As one example, buttstock assembly 104 can also,optionally, include a retraction member 224 that can be received onsecond end 208 of retaining member 190 and secured thereto in anysuitable manner, such as by using a threaded nut 226 to engage aplurality of threads (not numbered) on the second end of the retainingmember, for example.

Buttstock assembly 104 can be assembled in any suitable manner. Forexample, buttstock frame 128 can be provided that includes first passage144, second passage 174 and third passage 184. Transfer member 188 canalso be provided and inserted into second passage 174 until opening 194in the transfer member is in approximate alignment with third passage184. Optionally, a biasing member, if provided, can be inserted intosecond passage 174 together with transfer member 188. Retaining member190 can then be inserted into third passage 184 in any suitable manner.As one example, fourth passage 186 can be of sufficient size to permitfirst end 206 of retaining member 190 to pass through the fourth passageand into third passage 184. In such case, retaining member 190 can beoriented such that second end 208 is disposed toward top portion 138 andfirst end 206 is disposed outwardly and away from the top portion. Theretaining member can then be axially displaced through fourth passage186 and into third passage 184 such that the retaining member extendsthrough opening 194 in transfer member 188 and second end 208 projectsoutwardly from bottom portion 140 of buttstock body 128. A biasingmember, if provided, can be installed within third passage 184 (or,alternately, along second outer surface 212 of the retaining member)prior to insertion of the retaining member into the third passage. Aretraction member, such as retraction member 224, for example, can thenbe secure on second end 208 of the retaining member in any suitablemanner, such as by way of threaded nut 226, for example.

During use, first outer surface 210 of first end 206 is in abuttingengagement with one of cavities 126 as well as inner side wall 192 oftransfer member 188. Additionally, at least a portion of at least oneouter side wall (e.g., one of outer side walls 196) of transfer member188 is in abutting engagement with a corresponding side wall ofbuttstock body 128 (e.g., a corresponding one of side walls 180 and182). This arrangement permits a force applied to the buttstock (e.g.,an impact load due to an alternative use of the firearm) to betransmitted through buttstock frame 128 to transfer member 188. Innerside wall 192 of the transfer member engages first outer surface 210 offirst end 206 of retaining member 190 to transfer at least a portion ofthe force to the retaining member. The retaining member can then reactthe force into firearm 100 through abutting engagement with one ofcavities 126 of receiver extension 102. Forces acting in the opposingdirection (e.g., forces due to recoil) would be transferred to thebuttstock body in the same manner.

Buttstock assembly 104 can also include a buttpad assembly 228 that canact as a cushion for bracing firearm 100. However, buttpad assembly 228differs from other known buttpad constructions in that buttpad assembly228 includes feature that acts as a strike guard and wear surface forthe buttstock assembly. It will be appreciated that a buttpad assemblyin accordance with the subject matter of the present disclosure can beof any suitable type, kind, arrangement, configuration and/orconstruction and that any other features and/or element can also beincluded thereon.

In the exemplary arrangement shown herein, buttpad assembly 228 includesa base wall 230 adapted to extend longitudinally along at least aportion of end wall 154 of buttstock body 128. Additionally, base wall230 extends widthwise across the end wall and can, optionally, includethe approximate outer peripheral shape of at least a portion of end wall154. Buttpad assembly 228 also includes a cushion or pad 232 thatextends along and across base wall 230. It will be appreciated that basewall 230 and cushion 232 can be formed from any suitable materials orcombination of materials. As one example, base wall 230 can be formedfrom a substantially rigid material, such as a high strength polymer ora metal, for example, and cushion 232 can be formed from a compliantmaterial, such as a thermoplastic elastomer, for example. Additionally,it will be appreciated that cushion 232 can be secured on or along basewall 230 in any suitable manner. As one example, cushion 232 could besecured on or along base wall 230 using a suitable securement feature orelement, such as a threaded fastener or an adhesive, for example. Asanother example, base wall 230 could include a plurality of holes 234formed therethrough and cushion 232 could be over-molded onto base wall230 with a portion of the material used to form the cushion flowing intoholes 234 to secure the cushion on the base wall.

More specifically, base wall 230 is shown as including a first portion236 that can be substantially planar or otherwise complimentary to endwall 154 and a second portion 238 that is spaced lengthwise from thefirst portion. Second portion 238 is shown as being disposed at an angleAG1 relative to first portion 236. It will be appreciated that anysuitable angle can be used. For example, angle AG1 could be within arange of approximately 5 degrees to approximately 85 degrees.Additionally, second portion 238 is shown as being offset from firstportion 236 such that a shoulder portion 240 extends therebetween.

Buttpad assembly 228 also includes a guard element 242 that extends frombase wall 230 toward and along bottom portion 140 of buttstock body 128.Guard element 242 includes an outer surface 244 that is preferablypositioned as the bottommost surface of buttstock assembly 104, as isgenerally represented by reference dimension BTM (FIG. 3), such thatouter surface 238 can be used as a rest for contacting a supportingsurface (e.g., dirt, rock and concrete) during use of the firearm. Assuch, it is desirable for guard element 242 to be formed from a materialhaving suitable wear resistance and/or other desirable strength andabrasion resistance properties. As one example, guard element 242 couldbe formed from metal (e.g., steel and aluminum).

It will be appreciated that guard element 242 can be formed or otherwiseprovided in any suitable manner. For example, the guard element could beformed together with base wall 230 such that an integral base wall andguard element component is provided. As another example, guard element242 can be provided as a separate component, as is shown herein, andsecured or otherwise attached to base wall 230 using suitable securementfeatures and/or devices, such as threaded or non-threaded fasteners,adhesive and/or a flowed material joint (e.g., a welded or brazedjoint), for example. One benefit of using such a two-part constructionis that a robust guard element can be provided while adding minimalweight to the buttstock assembly.

It will be appreciated that buttpad assembly 228 can be secured on oralong buttstock body 128 in any suitable manner. As one example, buttpadassembly 228 can be secured on buttstock body 128 at a first or lowerpoint 246 along bottom portion 140 of the buttstock body and at a secondor upper point 248 spaced heightwise from the first point toward topportion 138 of buttstock body 128. In the exemplary arrangement shown,bottom wall 156 that extends along bottom portion 140 of buttstock 128includes an opening formed therein that is suitable for receiving andabuttingly engaging guard element 242. As shown, bottom wall 156includes a first opening or cavity 250 formed along one side of thebuttstock body and a second opening or cavity 252 formed along theopposing side of the buttstock body such that an intermediate wall 254is disposed therebetween.

Guard element 242 is preferably cooperable with the one or more openingsprovided in buttstock body 128 to secure buttpad assembly 228 thereon ator along first mounting point 246. In the exemplary arrangement shown,guard element 242 is somewhat J-shaped and forms a hook that is adaptedto engage the buttstock body. Guard element 242 includes a first wallportion 256 that is adapted for connection to base wall 230, such as hasbeen described above, and a second wall portion 258 disposed at theopposite end of the guard element from first wall portion 256. A slot orgroove 260 is formed into second wall portion 258 such that two endportions or hooks are formed from second wall portion 258. Preferably,slot 260 is complimentary to intermediate wall 254 such that theintermediate wall can be received within the slot as the hooks formed onsecond wall portion 258 are received into first and second openings 250and 252. The interengagement of the hooks formed by second wall portion258 with openings 250 and 252 in the buttstock body acts to restrict atleast longitudinal displacement of the buttpad assembly along bottomportion 140 and the interengagement of intermediate wall 254 with thehooks formed by second wall portion 258 acts to restrict widthwisemovement of the buttpad assembly. In this manner, buttpad assembly 228can be secured on or along buttstock body 128 at first mounting point246.

As mentioned above, buttpad assembly 228 can be secured on or alongbuttstock frame 128 at second mounting point 248 in any suitable manner.As one example of a suitable mounting arrangement, base wall 230 caninclude a mounting hole 262 that is disposed in approximate alignmentwith a suitable securement feature (not shown) to engage buttstock body128. It will be appreciated that such a securement feature can beprovided separately or integrally formed on the buttstock body. Cushion232 can include an access cavity 264 formed therein that permits asuitable securement device (not shown) to be installed through mountinghole 262 to engage the buttstock body or separate securement featuresupported thereon. In this manner, buttpad assembly 228 can bereleasably secured on the buttstock body and can be removed forreplacement or repair.
